DESCRIPTION OF EXAMPLE EMBODIMENTS

Overview

Techniques are provided herein for secure display device communications. In one example embodiment, a video communications device provides, to a display device over a first connection, communication information that enables the display device to contact a server over a second connection. The video communications device further provides, to the display device over the first connection, a command configured to initiate an interaction with the server. The server obtains, from the display device over the second connection, a message initiating the interaction in response to the command based on the communication information.

EXAMPLE EMBODIMENTS

FIG. 1 illustrates a block diagram of an example system 100 configured for secured display device communications. System 100 includes display device 105, video communications device 110, Local Area Network (LAN) 115, and Wide Area Network (WAN) 118. Display device 105 includes Ethernet ports (e.g., auxiliary Ethernet ports) 120(1) and 120(2), and High-Definition Multimedia Interface (HDMI) port (e.g., auxiliary HDMI port) 125. Video communications device 110 includes camera 130, speakers 135, microphone 140, and optionally server (e.g., web server) 150. Video communications device 110 further includes HDMI port (e.g., auxiliary HDMI port) 155 and Ethernet ports (e.g., auxiliary Ethernet ports) 160(1) and 160(2). LAN 115 includes a plurality of LAN switches 165(1)-165(N) and optionally server 150. System 100 also includes an HDMI connection (e.g., HDMI Consumer Electronics Control (HDMI-CEC) connection) 170 between display device 105 and video communications device 110. HDMI connection 170 may be enabled by an HDMI cable connected to HDMI port 125 and HDMI port 155. WAN 118 may optionally include server 150.

In this example, display device 105 is a third-party display device that is deployed with video communications device 110 to provide coordinated video communications services for a user. In particular, display device 105 may provide video output capabilities (e.g., via a display screen, such as a Light-Emitting Diode (LED) screen), and video communications device 110 may provide video input capabilities via camera 130, audio output capabilities via speakers 135, audio input capabilities via microphone 140, and video and/or audio compression/encoding and decompression/decoding capabilities via codec functionality. Thus, for example, video communications device 110 may receive audio and video signals from a far-end device, output the audio signals via speakers 135, and transmit video signals over HDMI connection 170 for output on display device 105.

Server 150 may include software that provides display device 105 with one or more services (e.g., software or firmware download service, configurable setting read/write service, debugging log management service, display telemetry data processing service, etc.). In one example, video communications device 110 hosts server 150. In this example, server 150 may include software that is integrated with (e.g., located in a memory of) video communications device 110. Alternatively, in another example, video communications device 110 is not configured to host server 150. For instance, server 150 may be a stand-alone server (e.g., with independent/dedicated memory and computing resources) or may be software that is integrated with one or more other network-connected devices of which video communications device 110 is aware. If video communications device 110 is not configured to host server 150, server 150 may be located in LAN 115 or WAN 118, for example, as a stand-alone server or integrated with one or more other network-connected devices.

A user of a video communications system would expect that system to meet user needs regardless of whether a display device and a video communications device in the system were produced by different manufacturers. If the display device and video communications device cannot properly interact on the display device and/or video communications device (e.g., due to problems such as suboptimal settings, software bugs, security holes, etc.), the system would not meet user expectations. Therefore, it is important for the display device and video communications device to be operationally compatible.

However, an Information technology (IT) administrator responsible for a conventional video communications system would find it difficult to ensure that the display device used in the system is running up-to-date software and has settings that cause the display device to operate correctly in conjunction with the video communications device. This task can be particularly cumbersome when the system includes a multitude of display devices and video communications devices.

Furthermore, conventional video communications systems only communicate over an HDMI connection, which is ill-suited for providing automated management of a display device. For example, consider a scenario in which the video communications device needs to provide a software upgrade of the display device. An HDMI cable would not be feasible for that task because the technology is too primitive. HDMI-CEC can only support a bit rate of 400 bytes per second, whereas software images for display device software upgrades can be hundreds or even thousands of megabytes. Thus, conventional video communications systems cannot adequately manage display devices in an automated and practical manner.

Accordingly, described herein are techniques for initiating and facilitating automated management of display device 105 in a scalable and secure fashion. In one example, system 100 further includes Internet Protocol (IP)/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2). IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2) may establish a high-bandwidth IP link between display device 105 and video communications device 110 via an Ethernet cable. IP/Ethernet connection 175(1) may be enabled by video communications device 110 exposing an IP subnet that is accessible via Ethernet port 160(1) to which display device 105 is physically connected (e.g., by an Ethernet cable) at install time. IP/Ethernet connection 175(2) may be enabled over LAN 115 (e.g., over one or more of LAN switches 165(1)-165(N)). IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2) may be suitable for secure, automated management of display device 105, such as software upgrades.

Video communications device 110 also includes secure communication logic 180 which may cause video communications device 110 to perform operations described herein. Briefly, in one example, video communications device 110 may use HDMI connection 170 to initiate or bootstrap an outbound Hypertext Transfer Protocol (HTTP) or HTTP Secure (HTTPS) call/request over IP/Ethernet connection 175(1) or IP/Ethernet connection 175(2) from display device 105 to video communications device 110. In particular, video communications device 110 may provide, to display device 105 over HDMI connection 170, communication information that enables display device 105 to contact server 150 over IP/Ethernet connection 175(1) or IP/Ethernet connection 175(2). The communication information may point to any given location of server 150 (e.g., video communications device 110, LAN 115, WAN 118, etc.). Video communications device 110 may also provide, to display device 105 over HDMI connection 170, a command configured to initiate an interaction with server 150. Server 150 may obtain, from display device 105 over IP/Ethernet connection 175(1) or IP/Ethernet connection 175(2), a message initiating the interaction in response to the command based on the communication information.

In addition to overcoming the technical limitations of HDMI connection 170 by escalating to higher-bandwidth IP/Ethernet connection 175(1) or IP/Ethernet connection 175(2), these techniques also provide security benefits. Because HDMI connection 170 initiates an action on display device 105, display device 105 does not need to open any additional listening network IP ports/interfaces on the active network to obtain the command. Such network ports/interfaces could be accessible by any entity connected to the active network, which is an inherent security risk. Because server 150 is already running, there is no need to open additional network ports which would carry associated security risks. One reason that server 150 is already running may be that server 150 is used for various remote administration tasks related to video communications device 110, for example, in the case where server 150 is integrated with video communications device 110.

Moreover, no additional hardware changes are necessarily required on display device 105 or video communications device 110. This scheme also enables flexible and secure machine-to-machine communication between display device 105 and video communications device 110, which may be used to guarantee user experience and improve maintainability/manageability/serviceability of system 100. It will be appreciated that the techniques described herein may apply to any suitable device, such as a Cisco Webex Room Kit, video streaming box, etc.

The communication information may indicate how display device 105 can reach video communications device 110, such as the IP address of server 150. The command may prompt display device 105 to perform some function/operation involving server 150, which may be running on the IP interface of video communications device 110. The communication information and command may be included in any suitable number of messages. In one example, the communication information and command may be included in one message. In another example, the communication information may be included in a first message and the command may be included in a second message.

In one example, the command may include a command to download software or firmware from server 150 (e.g., “fetch software and perform software upgrade”). Video communications device 110 may download the software image/package for display device 105 before display device 105 fetches the software image/package. In another example, the command may include a command to read or write at least one configurable setting of display device 105 from or to server 150 (e.g., “write/export configurable settings,” “read/import configurable settings,” etc.). Server 150 may extract settings used by display device 105, such as settings that impact latency, color representation, and/or power control. In still another example, the command may include a command to provide (e.g., write, export, etc.) a debugging log (e.g., an internal log file useful for debugging) to server 150.

In yet another example, the command may include a command to provide display telemetry data to server 150. The display telemetry data may include telemetry data relating to display device 105, and video communications device 110 may adjust display data sent to display device 105 based on the display telemetry data. For instance, the display telemetry data may include data indicating that the brightness of blue LEDs of display device 105 decreases over time due to inherent physical characteristics of the blue LEDs. In this case, video communications device 110 may compensate for the decrease in the brightness of blue LEDs by increasing the brightness of blue colors in the display data, and sending the display data over HDMI connection 170 for display device 105 to generate video based thereon. Video communications device 110 may also/alternatively provide the display telemetry data to the manufacturer of display device 105.

Additional mechanisms may be employed to further bolster security. In one example, video communications device 110 may provide information (e.g., details) regarding a security certificate (e.g., an HTTPS certificate) to be presented to display device 105 by server 150. Video communications device 110 may provide the information regarding the security certificate in the same message that includes the communication information and/or command, or in a separate message. Server 150 may further present the security certificate to display device 105, for example over IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2) in response to display device 105 initiating the interaction with server 150. Display device 105 may determine whether the security certificate matches the information regarding the security certificate, and if there is a match, display device 105 may identify server 150 as a trusted entity. If there is no such match, display device 105 may take any suitable action, such as refraining from carrying the interaction forward, generating an alert, etc. In one specific example, display device 105 may use the information to authenticate that the security certificate was sent by server 150.

In another example, video communications device 110 may share security credentials with display device 105 to enable display device 105 to initiate the interaction with server 150. Video communications device 110 may initially share the security credentials such that display device 105 can reach video communications device 110 over IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2). In still another example, video communications device 110 may encrypt the communication information provided over HDMI connection 170 and/or the command provided over HDMI connection 170 with a key that is pre-shared with display device 105. The key may be pre-shared with the display manufacturer, which may manufacture display device 105 to include the pre-shared key. Pre-sharing the key may decrease the likelihood of any unwanted eavesdropping or copying.

While the specific example of system 100 includes HDMI connection 170, it will be appreciated that any suitable first connection may be utilized to employ the techniques described herein. In one example, the first connection may be any suitable wired connection (e.g., HDMI, Universal Serial Bus (USB), serial communication, etc.) or wireless connection (e.g., Wi-Fi®, Bluetooth®, etc.). The first connection may involve video communications device 110 being in physical proximity to display device 105, such as a wired connection that involves physical proximity (e.g., HDMI, USB, etc.) or a wireless connection that involves physical proximity (e.g., Bluetooth, etc.). The physical proximity may serve as a security feature to ensure that display device 105 can trust video communications device 110. For instance, a bad actor would require physical proximity to video communications device 110 to bypass this security feature. In another example, the first connection may be any suitable low-bandwidth connection (e.g., HDMI). In another example, the first connection may be any suitable peer-to-peer connection (e.g., Wi-Fi, Bluetooth, etc.).

Furthermore, while the specific example of system 100 includes IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2), it will be appreciated that any suitable second connection may be utilized to employ the techniques described herein. In one example, the second connection may be any suitable high-bandwidth connection. In the specific example where the second connection is an IP connection, the second connection may be a wired connection (e.g., Ethernet) or wireless connection (e.g., Wi-Fi). Any suitable communication information may be used depending on the connection type of the second connection. For example, if the second connection includes a Wi-Fi connection (e.g., a Wi-Fi connection that uses a Wi-Fi peer-to-peer protocol), the communication information may include a Wi-Fi identifier of video communications device 110/server 150. The communication information may also/alternatively include a Media Access Control (MAC) address of video communications device 110/server 150. If the second connection includes a Wi-Fi connection, the security credentials may include credentials for a Wi-Fi network. If the second connection includes a peer-to-peer connection, the security credentials may include some secret that can be used to establish a peer-to-peer connection.

In one example, the first connection and the second connection are a common connection (e.g., the same connection). The common connection may be any suitable high-bandwidth connection that is trusted by both video communications device 110 and display device 105. The common connection may a wired connection, such as Thunderbolt™, USB (e.g., USB3), Ethernet, etc., or a wireless connection, such as Wi-Fi. In one specific example, the common connection is an IP connection established using a secure protocol. In this example, a service (e.g., a proprietary service) may run on an open IP port of display device 105, and video communications device 110 may send the communication information and/or the command over IP to the IP port using the service. Other alternatives to HDMI connection 170 and IP/Ethernet connection 175(1) and/or IP/Ethernet connection 175(2) may be envisioned.

With continuing reference to FIG. 1 , FIG. 2 illustrates a flowchart of an example method 200 for securing communications with display device 105. At operation 210, video communications device 110 sends one or more messages over HDMI connection 170 to display device 105. The one or more messages include communication information that enables display device 105 to contact server 150 over IP/Ethernet connection 175(1) or IP/Ethernet connection 175(2) and a command configured to initiate an interaction with server 150. At operation 220, display device 105 initiates the interaction with server 150 based on the one or more messages (e.g., a request for a software update). At operation 230, server 150 performs one or more operations in accordance with the interaction (e.g., providing a software image for the software update).
